The Snapmaker U1 brings the toolchanger under $1,000. Where an AMS or CFS purges on every color change, the U1 gives each filament its own complete toolhead and swaps them mechanically — hence 5× less waste and ~5-second changes. Its record crowdfunding (over $20M) confirms the market's appetite for clean, affordable multicolor.
It's the "toolchanger" approach like the Prusa XL, but far more affordable and with 4 heads. Also compare with the dual-nozzle Bambu H2D; it's all put in perspective in our multi-tool landscape.
In brief
An enclosable CoreXY, 4 heads, 270 mm volume, 500 mm/s: the U1 targets "serious" multicolor without the waste of single-nozzle systems, nor the price of a Prusa XL. Launched April 10, 2026, at ≈ $849 (≈ $899 at the regular price).

SnapSwap: 4 heads
The SnapSwap system carries four heads, each with its filament pre-loaded and pre-heated. On a color/material change, the machine docks the active head and grabs another in ~5 seconds, without purging filament through a shared nozzle. Benefits:
- ~80% less waste than a multicolor single-nozzle system.
- Up to 5× faster on prints with frequent changes (no purge wait).
- Mixed materials: you can combine different materials (e.g. soluble support) on the same part.
U1 vs Prusa XL
Same principle (toolchanger), different positioning. The Prusa XL offers up to 5 heads, a large volume (360 mm), a segmented bed and Prusa's open-source ecosystem — at a much higher price. The U1 offers 4 heads, a more compact volume (270 mm) and a far lower price. For anyone wanting to taste toolchanging without the XL investment, the U1 is the logical entry.
Limits
- New product: launched April 2026; ecosystem, long-term reliability and profiles still maturing (early reviews note good performance "with caveats").
- 4 colors max: fewer than the INDX's 8 or a chained AMS's 16 — but without the purge.
- Footprint & weight: 18.2 kg, a sizeable machine.
- Swap mechanics: more moving parts than a single nozzle, so potentially more maintenance.
Who's it for?
The U1 is for those who want clean, fast multicolor/multi-material without paying for a Prusa XL or suffering AMS/CFS waste. For large volume and 5 heads, see the XL; to understand all approaches and choose, the multi-tool landscape.
The toolchanger that makes waste-free multicolor affordable — 4 heads, ~5 s per swap, under $1,000.
